Back to Basics: C++ API Design - Jason Turner - CppCon 2022
https://github.com/CppCon/CppCon2022
Let’s face it: writing a C++ API can be a daunting task. You recognize that APIs are a critical aspect of your code, and you’d like to provide your users with a great experience, but how?
This talk will focus on one key aspect: "Making APIs Hard to Use Wrong." How do we design APIs that help, instead of hurt, our users?

Using Modern C++ to Eliminate Virtual Functions - Jonathan Gopel - CppCon 2022
https://github.com/CppCon/CppCon2022
As of C++20, there are no cases in which statically linked programs require virtual functions. This talk will explore techniques for replacing runtime polymorphism with compile-time polymorphism such that virtual functions are never necessary. This talk will also address the higher-order concern of when it might make sense to avoid virtual functions or remove them from a codebase, as that decision ultimately is a design decision that only the author of the code can make. Attendees can expect to come away with a stronger understanding of the purposes of virtual functions and the mechanisms in modern C++ that can now be used to achieve those same purposes.

C++ for Enterprise Applications - Vincent Lextrait - CppCon 2022
https://github.com/CppCon/CppCon2022
C++ is paradoxical, it has one of the largest shares of the number of back-end transactions processed in the world (possibly the largest), most of the large Enterprise Applications are C++-based, and C++ has one of the smallest in number of Enterprise Applications (Source: SlashData, "State of the Developer Nation" 22nd Edition, Q1 2022).
The presentation offers an explanation of why this is the case, and shows a number of high-level abstractions examples that we developed and that can leverage C++ unique meta cppcon.digital-medium.co.uk/tag/programming/">programming capabilities and resolve long-running issues that Enterprise Application developers face, namely:
- How to build a sophisticated Referential Integrity system, abstracted from document databases, which is more powerful and faster that what relational databases offer today, and can be specified in a very concise manner (an ontology).
- How this Referential Integrity offers as a byproduct automatic objects destruction, in a way which is much faster than Garbage Collection techniques, more frugal than reference counting with the same guarantees, and without deadlocks.
- How to replace SQL with fast compiled C++ functions attached to semantic attributes declared in C++ classes.
- We propose to give also a glimpse (without details) of numerous additional useful Enterprise Applications-related abstractions that C++ meta cppcon.digital-medium.co.uk/tag/programming/">programming allows.

C++ MythBusters - Victor Ciura - CppCon 2022
https://github.com/CppCon/CppCon2022
The C++ community is very large and quite vocal when it comes to controversial issues.
We’re very fragmented on many topics, based on the breadth of the C++ ecosystem and the background/experience we each bring from our C++ niche.
From CppCoreGuidelines to opinionated best practices to established idioms, there’s a lot of good information easily available. Mixed up with all of this there are also plenty of myths. Some myths stem from obsolete information, some from bad teaching materials.
In this presentation, I will dissect a few of the most popular C++ myths to a level of detail not possible on Twitter… and without the stigma of newb/duplicate/eyeroll one might experience when asking these questions on StackOverflow.
Expect the familiar “Busted”, “Plausible”, or “Confirmed” verdicts on each myth and come prepared to chat about these.

Back to Basics: C++ Value Semantics - Klaus Iglberger - CppCon 2022
https://github.com/CppCon/CppCon2022
Modern C++ is more than new standards or an assortment of new features. Modern C++ is about a philosophy on how to use the language. An integral part of this philosophy is value semantics: preferring values and value-like types instead of pointers and references.
This talk explains the rational of this philosophy. It demonstrates the benefits of several value types from the standard library, such as std::optional, std::function and std::variant, and the drawbacks of several reference types, such as std::string_view and std::span. It also goes into detail about the most common questions about value semantics, as for instance how to properly use reference types and whether we should stop using reference parameters.

The Imperatives Must Go! [Functional Programming in Modern C++] - Victor Ciura - CppCon 2022
https://github.com/CppCon/CppCon2022
Can a language whose official motto is “Avoid Success at All Costs” teach us new tricks in modern C++ ?
If Haskell is so great, why hasn't it taken over the world? My claim is that it has. But not as a Roman legion loudly marching in a new territory, rather as distributed Trojan horses popping in at the gates, masquerading as modern features or novel ideas in today’s mainstream languages. Functional Programming ideas that have been around for over 40 years will be rediscovered to solve our current software complexity problems.
Indeed, modern C++ has become more functional. From mundane concepts like lambdas & closures, std::function, values types and constants, to composability of STL algorithms, lazy ranges, folding, mapping or even higher-order functions in STL. Did I mention Rust yet?
In this session we’ll analyze a bunch of FP techniques in C++ and see how they help make our code shorter, clearer and faster, by embracing a declarative vs. an imperative style. We’ll visit the functional parts of current STL, use algebraic data types (ADT) and learn about the new FP stuff coming in the next C++ standard, like ranges or monadic extensions to std::future, std::optional and std::expected. Brace yourselves for a bumpy ride including composition, lifting, currying, partial application, pure functions, maybe even pattern matching and lazy evaluation.
